Definitions

  • the invention relates to a belt drive consisting of a toothed belt and a toothed pulley according to the preamble of the claim.
  • toothed belts are guided laterally when rotating around a toothed pulley between two side flanges of the toothed pulley.
  • toothed belt drives for example when using the toothed belt as a transport element in transport systems, in which the toothed pulley cannot protrude laterally over the toothed belt with flanges. For this, e.g. B.
  • a self-guiding toothed belt in which a strand-shaped guide rib is arranged along the center line of the toothed belt side, which engages in a matching annular groove at the center of the toothed peripheral surface of the toothed pulley, or in which the toothed belt side conversely is divided into two rows of toothed ribs by a guide groove running in the longitudinal direction of the belt and a circumferential rib of the toothed pulley engages in the groove, in order thereby to guide the toothed belt laterally on the toothed pulley even without flanges.
  • a disadvantage of this known toothed belt is that the strand-shaped guide rib of the toothed belt must be compressed on the inside of the curve of the toothed belt when rotating around toothed pulleys, which despite the notches provided in the known toothed belt on the guide rib impairs the desired soft flexibility of the toothed belt and leads to an unfavorable running behavior of the timing belt on the pulley.
  • the known toothed belt has the disadvantage that the force transmission surface on the through the strand-shaped guide rib or through the longitudinal guide groove of the toothed belt Flanks of the toothed ribs is reduced, so that in order to be able to transmit the same drive power as without the guide rib or without the guide groove, the toothed belt must be made wider, which makes the belt more expensive and as a result the circulation of the toothed belt around a toothed pulley also becomes louder.
  • the invention has for its object to provide a toothed belt for a toothed belt drive of the type mentioned, which secures itself against lateral runout on a toothed pulley without the guide rib or the guide groove of the known self-guiding toothed belt and thus avoids the reduction of the force transmission surface by the guide rib or guide groove .
  • the toothed belt 1 shown in FIG. 1 made of plastic or similar extrudable material, in the belt body 2 of which a tensile reinforcement insert 3 is embedded, is formed with a toothed belt side consisting of toothed ribs 4 and toothed grooves 5, which in the exemplary embodiment shown are in three strips side by side lying rows 6, 7 and 8 is divided by toothed rib sections.
  • the narrower middle row 7 is offset in relation to the two adjacent rows 6 and 8 in the belt longitudinal direction or in the direction of the tooth pitch such that the toothed rib sections 4 a of the middle row 7 are at least partially to the side of the tooth grooves 5 of the two side rows 6 and 8.
  • the toothed rib sections 4b of the rows 6 and 8 are laterally next to the tooth grooves of the row 7.
  • the toothed rib sections 4a are offset by half the tooth pitch relative to the toothed rib sections 4b, so that the toothed rib sections each have the full cross section laterally next to the tooth grooves of the adjacent ones Row.
  • the force transmission area of the belt toothing on the tooth flanks 9 is not reduced and is on both ends of the toothed rib sections 4a of the central strip 7 and also on the adjacent ends of the toothed rib sections 4b of the side strips 6 and 8 transverse to the toothed ribs 4 and toothed grooves 5 of the belt toothing guide surfaces 20 are formed, with which the toothed belt automatically leads on a suitably designed toothed pulley, so that the toothed pulley does not have any lateral flanges protruding from the toothed belt to secure the toothed belt against lateral runoff needs to show.
  • the toothed belt can also have only two rows of toothed rib sections which are offset with respect to one another, in order to secure the toothed belt with the guide surfaces 20 of the two toothed rib rows facing one another in both lateral directions on a correspondingly designed toothed pulley against lateral runoff.
  • Toothed rib rows 6, 7, 8 of the belt toothing from three adjacent and interconnected toothed pulley sections 11, 12, 13 which are twisted to match the belt toothing, so that the guide surfaces 20, for example, the central toothed rib row of the belt toothing with those of the toothed ribs of the two side toothed pulley sections formed stop surfaces 21 cooperate for lateral guidance of the toothed belt.
  • the toothed rib rows 6, 7, 8 of the toothed belt 1 and the toothed pulley sections 11, 12, 13 of the toothed pulley 10 are advantageously matched in width in such a way that between the guide surfaces interacting for the lateral guidance 20 on the toothed belt teeth 4 on the one hand and the guide surfaces 21 on the toothed pulley teeth on the other hand there is a small predetermined distance in the belt transverse direction.
  • the exemplary embodiment of the toothed belt shown in FIG. 3 has five narrow rows 14 of toothed rib sections, of which two adjacent rows are offset from one another by half the tooth pitch in the belt longitudinal direction.
  • the rows 14 are preferably of the same width.
  • the toothed pulley shown in FIG. 4 which matches the toothed belt of FIG. 3, consists of five toothed pulley sections 15 lying next to one another and rotated relative to one another.
  • This design of the toothed belt and the associated toothed pulley has the additional advantage, in particular for large belt widths, that when the toothed belt rotates around Tooth pulley the air better and un hindered can escape from the tooth grooves receiving one tooth and thereby less noise is generated when the belt rotates around the toothed pulley.
